Isifinyezo Esisheshayo:
Isingeniso: Kungani “Ukungangeni Manzi” Kusho Izinto Ezihlukile Emaphaketheni Ojosaka Wokuqwala Izintaba Kubantu abaningi abaqwala izintaba, igama elithi “ukungangeni kwamanzi” lizwakala liqinisekisa. Iphakamisa ukuvikelwa, ukwethembeka, nokuthula kwengqondo lapho izimo zezulu zishintsha ngokungalindelekile. Nokho ekusebenzeni, ukuvimbela amanzi kumajosaka okugibela izintaba kuhluke kakhulu kunelebula eyodwa noma isici.
Izixazululo ezimbili eziyinhloko zisetshenziswa kabanzi namuhla: Izindwangu zikabhaka eziboshwe nge-PU futhi imvula yangaphandle ihlanganisa . Zombili zenzelwe ukuphatha umswakama, kodwa zisebenza ngezindlela ezihluke kakhulu, zisebenzisa izinhloso ezihlukene, futhi ziyehluleka ngaphansi kwezimo ezihlukene. Ukudideka kuvela lapho abaqwali bezintaba becabanga ukuthi lezi zixazululo ziyashintshana noma balindele ukuthi eyodwa ilethe ukusebenza okuphelele okungangeni manzi kuzo zonke izindawo.
Lesi sihloko sihlola ukusebenza komhlaba wangempela we ojosaka abahamba ngezinyawo abangangeni manzi I-PU coating vs ikhava yemvula ngesayensi yezinto zokwakha, ukucatshangelwa kwe-biomechanical, kanye nezimo zokuqwala izintaba ezivivinywe ensimini. Kunokuba kuthuthukiswe isixazululo esisodwa phezu kwesinye, umgomo uwukucacisa ukuthi uhlelo ngalunye lusebenza kanjani, lapho luhamba phambili khona, nalapho ukulinganiselwa kwalo kuba bucayi khona.
Ukuqonda lo mehluko kubalulekile. Ukucatshangelwa okungalungile mayelana nokuvinjelwa kwamanzi kuvame ukuholela egiyeni elicwilisiwe, ukuncipha kokuqina komthwalo, kanye nokonakala kwezinto ngaphambi kwesikhathi—ikakhulukazi phakathi nohambo lwezinsuku eziningi noma izinga lokushisa elidlulele. Ekupheleni kwalo mhlahlandlela, uzoba nohlaka olusebenzayo lokunquma ukuthi nini I-PU enamathela , imvula ihlanganisa , noma a indlela ye-hybrid kwenza umqondo kakhulu.
Izimo zangempela zokuhamba izintaba ziveza ukuthi ojosaka abambozwe nge-PU namakhava emvula asebenza ngendlela ehlukile ngaphansi kwemvula enamandla ethatha isikhathi eside emizileni yezintaba.
Ukuqonda Ukuvimbela Amanzi Ezikhwameni Zokuqwala Izintaba Ukumelana Namanzi vs Ukungangeni Manzi: Izincazelo Zezobuchwepheshe Emishinini yangaphandle, ukuvinjelwa kwamanzi kukhona ku-spectrum kunokuba kube yisimo esimbambili. Iningi ojosaka abahamba ngezinyawo bangene esigabeni se amasistimu amelana namanzi , hhayi iziqukathi ezivalwe ngokugcwele.
Ukumelana kwamanzi kuvame ukukalwa kusetshenziswa izilinganiso zekhanda le-hydrostatic , kuvezwe ngamamilimitha (mm). Leli nani limelela ubude bekholomu yamanzi indwangu engamelana nayo ngaphambi kokuvuza.
Amabhentshimakhi ajwayelekile afaka:
1,000–1,500 mm: ukumelana nemvula encane
3,000 mm: ukuvikelwa kwemvula okuqhubekayo
5,000 mm nangaphezulu: ukumelana namanzi anomfutho ophezulu
Kodwa-ke, izilinganiso zendwangu zizodwa azichazi ukusebenza okuphelele kokuvikela amanzi. Ukuthunga, imithungo, oziphu, izimbobo zokudonswa kwentambo, nezindawo zokuhlangana zamaphaneli angemuva kuvame ukuba yizindawo zokungena emanzini kudala ngaphambi kokuthi kwenzeke ukwehluleka kwendwangu.
Kungani "I-100% Isikhwama Esingenamanzi" Ingavamile Ukuba Khona Ubhaka wokuhamba ngezinyawo uyisakhiwo esivumelana nezimo, esithwala umthwalo. Ngokungafani nezikhwama ezomile, kufanele igobe, icindezele, futhi ishintshe ngesikhathi sokunyakaza. Lawa mandla ashukumisayo abeka engcupheni ukuvalwa kwesikhathi.
Ukunyakaza kwe-torso okuphindaphindiwe kwandisa ingcindezi kuma-seams. Izintambo zamahlombe namabhande e-hip kudala izindawo ezicindezelayo. Ngisho nendwangu engangeni manzi, ukungena kwamanzi kuvame ukwenzeka:
Ngenxa yalokho, iningi ojosaka abahamba ngezinyawo
